完备图像稀疏表示是一种最新的图像表示模型,采用过完备字典中原子的线性组合形式实现图像的稀疏表示.传统
的过完备图像稀疏表示模型采用重建误差的平方和作为保真项.该保真项没有充分考虑到人眼对图像的感知特性,无法度量图
像中边缘、轮廓、纹理等局部几何结构的变化.本文基于过完备稀疏表示理论思想,建立了新的稀疏性正则化的图像稀疏表示模
型.模型中的正则项约束图像表示系数的稀疏性,保真项采用更符合视觉感知的结构相似性度量.基于正交匹配追踪算法,提出
了基于结构相似度的正交匹配追踪算法.实验结果表示,新的模型能够更好地重构图像的结构信息,获得更好的重建视觉效果.

OFDM-MATLAB
这里面有两个程序,两个都是采用4QAM调制。不过个人觉得第一个更容易懂,因为写的很有条理。我改的那个程序就是根据这个来的。
不过在这里面有个问题就是信道系数只能是由高到低,大家可以试试,改成[0.227 0.46 0.688 0.46 0.227]这个是老师给我的仿真中常用的信道系数,这个成为归一化信道,就是系数平方和为1.
第二个程序没有涉及到信道系数,但是这个程序当中,在128个子载波中,前后有32个空载波,这个在OFDM中也是经常用的,这样可以降低误码率。
(And there are two programs, two are based on 4QAM modulation. But personally feel that the first is easier, because the writing is organized. I changed that procedure is based on the past. However, there is a problem in that there is only channel coefficients from high to low, we can try and change into [0.227 0.46 0.688 0.46 0.227] This is the teacher gave me the simulation channel coefficient commonly used, this became normalized channel, is coefficient of the square and is 1. The second program is not related to channel coefficients, but this program which, in the 128 sub-carriers, the before and after the 32 air carriers, the in OFDM is also often used, which can reduce the error rate.)
